HEARD NOTHING FOR OVER A MONTH

I handed in my cell phone at the Telkom Direct Store in Menlyn on 4/09/2015 for the speaker to be fixed. I have a Telkom Mobile contract. I have heard nothing to date. I called the shop 56 times with no answer. I decided to take time off work on the 7th May to in to Menlyn to find out what is going on. The person who helped me called Solomon on the phone as he was not in the shop, I got no clear answer as to where my cell phone was, why it wasn't yet repaired, and why I hadn't heard from them. The lady said she would get back to me the following day after investigating. I have still heard nothing. Their phone line continues to remain unanswered. When I enquired as to why noone answers the phone, the lady said that the phone is at the back and they do not have a designated receptionist. I have been without my cell phone for over a month. Noone answers the phone. I am reluctant to again take time off work to deal with this issue.
